Definitions

  • the invention relates to a system for electrical contacting of tension members in suspension means to monitor suspension means in elevator systems.
  • belt-shaped suspension means In some conveyors such as elevator systems, cranes or hoists, belt-shaped suspension means are used. These support means generally comprise a plurality of beam wires consisting of tensile carriers which absorb the tensile forces to be absorbed by the suspension element.
  • the tension members are generally surrounded by a plastic sheath.
  • the jacket protects the tension members, for example against mechanical wear, because the support means are often guided over deflection points.
  • the jacket improves the traction of the suspension on Umlenkoder drive rollers, and fixed the arrangement of the tension members with each other.
  • Such suspension means are within a conveyor a safety-critical component. Their failure, or breakage can lead to a fall of the good to be promoted. This can lead to considerable property damage or personal injury. For this reason, test units are used in conveyors, which in particular check the mechanical condition of the tension members. Damage to the forces absorbing tension members should be able to be detected early, so that the support means can be replaced in case of damage to prevent failure of the conveyor.
  • the tension members are surrounded by the electrically insulating jacket made of plastic.
  • contacting of a contact element with the tension member is required in some methods.
  • an electrical current is passed with the aid of the contact element through the tension members, which serves as a test current to determine the state of the tension members.
  • other test methods that do not use electric current, e.g. Ultrasound, into consideration.
  • DE 3 934 654 A1 shows a generic type of suspension.
  • the ends of the tension members are connected in pairs conductive with a bridge part, so that the tension members of the support means are electrically connected in series.
  • the tension members of the suspension element are over an ammeter connected to a voltage source, so that by means of the test current, which is passed through all train carrier due to the electrical circuit in series, the state of the tension members can be assessed.
  • WO 2005/094249 A2 shows a system for contacting a suspension element, in which the contact elements pierce the jacket of the suspension element perpendicular to a longitudinal axis of the tension members and then penetrate into the tension members.

  • the contact element with the cutting side also has the advantage that the contact element can be driven like a knife through the jacket to contact the tension members.
  • a cutting side may be formed, for example, as a straight edge, or as a serrated edge with contact tips or as an edge with contact recesses or contact increases.
  • Such contact tips or contact recesses or contact increases have the advantage that the tension members can each be reliably contacted by a contact tip or contact recess or contact increase.
  • a contact tip or contact depression or contact increase per tensile carrier is provided in each case. As a result, all tensile carriers of a suspension element can be reliably contacted with a single contact element.
